Electronic Excitation of H₂ by Electron Impact Using Multichannel Static-Exchange-Optical Method

The momentum-space multichannel static-exchange-optical model is applied to the electron-H₂ collision at the two-state close-coupling level. Differential cross sections for X¹Σ_g to b³Σ_u transition at the energies of 20 and 30 eV are reported. Results are compared with other theoretical results and experimental data. Elastic scattering cross sections are also presented and compared with other work.
